Not surprised that a first iteration of a new feature has room for improvement. There's nothing magical about the Apple process for doing this. Colorimeters have been used for monitor adjustment for years by photographers. I use one. The phone in the case of the Apple TV is just running a simple routine to try to improve color balance. The feature will improve over time. I love this notion that any and all new features must be released with absolute perfection otherwise they will be declared an utter failure. And, honestly, a guy that makes his living overcharging for monitor calibration is never, ever going to say anything positive about a feature like this no matter who it is from.
He is not just "a guy".

He's not biased.
 
I tried it last night on my LG B7 OLED set to the out-of-the-box Technicolor setting in SDR and it actually said my screen was accurate and did not require calibration. Thanks Apple, I think so too!
 
The reviewer, Vincent Teoh, is very Apple-neutral: he’s praised Apple in the past, and he’s criticized them just as often. His primary review equipment costs north of $50k, so he can provide as-accurate-as-possible-answers.

After watching his video, my assumptions about Apple’s new ‘calibration’ feature were confirmed: if you care enough about accuracy to have already had your display calibrated (or at least did your own basic calibrations), then this feature won’t provide any benefit. But, for the 95% of average Joes and Janes who’ve never touched picture settings, this new feature will likely result in their display being more accurate.
 
If only there were a way to disable it if it makes the picture worse! That darn Apple, always forcing you to do changes that you might not want.

They should give you a choice for you to decide if you like the new settings better! /s

These days you will almost inevitably do worse than the factory.



Your perception is not that uncommon. I blame the ****wad manufacturers for this.

The manufacturers add interfaces that should not exist at times. Since those interfaces are exposed and user adjustable, people mess with them.

Settings such as gamma and unsharp masking have unambiguously correct values that generate reasonable output responses. If you mess with them, typically it just maps the range to fewer output values. There are various tests to see how well this is working, but beyond brightness levels, you really shouldn't be manually adjusting things on most televisions. If you buy it and it looks wrong, you should return it. You will be much happier in the long run that way.

edit: Keep in mind I wouldn't be telling you this on all parameters if they had meaningful controls. For example, if the hardware came with a way to adjust the color distribution of the backlight to emit a warmer or cooler tone, I wouldn't be against displaying color temperature as an option. The way it is now, these things can't do a good job of emulating such settings. Things like unsharp masking are different and should never be touched under any circumstance. There are rudimentary browser tests that ballpark how well your screen performs on some of these things though.
Obviously, I don't agree - my TV looks stunning after fine-tuning.

But you won't convince me and I won't convince you, and that's fine.

I bought a Sony x950h around April last year. To my eyes it looks fantastic out of the box. The only thing I change on it is TV channels. And I’ve had more than enough time with it watching regular TV, 4K HDR 10 and Dolby vision movies on disk as well as streamed, regular blue ray disks, and not once did I see anything that looked odd or weird or noticeably off to the point where I might want to fiddle with the picture settings. At the end of the day all I want is a great looking picture and not a picture that, well….I guess its supposed to look that way.
 
On my SONY TV the Apple calibrated picture is somewhat greenish. But I loved the calibration process itself. Best experience I've ever had with calibrating anything...
 
I spent some money getting my set calibrated. Much different look. Took some time to get used to a image that wasn’t bright enough to sunburn your face
Great investment. Adds years to ur TVs life
 
Just make your own TV already, Apple. You know it would sell extremely well.
I actually wish manufacturers would do the exact opposite. I want a screen only with multiple ports and ultra slim that will last, no speakers, no smart features or anything. Just a screen.
 
I used it on two TVs - very happy with the results. Of course I can always turn it off on the AppleTV, so why is the biggy? It seems people here are thinking that it actually resets the TV or something, NO, it modified the signal going to the TV. It might be that the impact of the "mis-calibration" are the current TV settings not being in some neutral territory.

But in any event, we can all stop whining now, and just turn it off, if you are not happy with it.
I’ll trust the professional calibrator, but glad it worked out for you.

That is correct. If you measure an output device, you can estimate (note estimate, because it doesn't guarantee an exact response, particularly given that people may not allow these to warm up sufficiently), however the input to the TV has a limited number of bits available. You can't do anything about that.

Also, any adjustments to the per channel range, which are the only way to achieve things like adjustment of white balance from a software perspective, work by shrinking the range of 1-2 channels, meaning you do in fact lose gamut.

That part is not correct. While consumer grade devices have gotten way better over the years for this type of stuff, you can't do very much with software based adjustments. They hit a wall very very fast, and you may not immediately realize this, as not all media covers the full range of what a typical television can display.
 
What does this even mean?

From the article itself:

"When set to their most accurate out-of-the-box color presets, two of the three TVs Teoh tested had their color accuracy made worse. On a Samsung QLED TV, the overall color accuracy improved, but the image was incorrectly shifted to a cooler blue tone."
It means what it says.

Every set is different mine looked like **** as did most I’ve read about. My set is on the upper scale of Samsung TV’s. I never thought it would or could do better but I gave it a whirl. You somehow think that paragraph you cut and pasted was good?
